Pulse Oximetry and COPD: A recent study performed by Salim S. Al-Ani compared Pulse Oximetry levels in healthy adults and in a sample of individuals with severe chronic obstructive pulmonary disease (COPD) in order to better understand the relation among PO, age, and gender in healthy adults. Salim used a BIOPAC MP150 with the OXY100E, RSP100C, EMG100C amplifiers and AcqKnowledge software to record PO levels, respiration trace, and surface EMG signals. Read Salim’s full paper here.
Non-invasive Recording of the Sternocleidomastoid Muscle: Non-invasive methods can often be used for the study of respiratory muscle signals to provide clinical information for the evaluation of the respiratory muscle function. A group of researchers in Spain recently evaluated the electrical activity of the sternocleidomastoid muscle recorded superficially by means of a concentric ring electrode (CRE) in bipolar configuration. The BIOPAC EMG100C amplifier was used to record 5 healthy individuals as they underwent a respiratory load test. Find the full study here.
Methyl ester-induced hypertension in rats: Researchers in Thailand examined the effect of Carthamus tinctorius (CT) extract plus captopril treatment on blood pressure, vascular function and a variety of other measurements in methyl ester-induced hypertension. Rats were treated with methyl ester for five weeks and given CT extract plus captopril for two consecutive weeks. AcqKnowledge software was used to record all hemodynamic measurements from rats.
